Extensions support for Vivaldi

Hello, vivaldi team folks! Could you please add some extensions support. From webkit or firefox or opera extensions market? I need some to block Ads and junky scripts, view site tech backend and check words translation in pop-up/tooltip by clicking. It solved by Ghostery, uBlock, instant translate extensions. Without possibility to use it in Vivaldi that's why I cant use this browser yet. Preferable platforms: linux, windows. Thanks.

You can download anything you want from the chrome web store
Those are my extensions so far.
